Afrighids

The Afrighids were an Iranian dynasty which ruled over Chorasmia from 305 to 995 AD, with Kath serving as their capital. The Afrighids adhered to Zoroastrianism until the 8th century AD, when the Umayyad general Qutayba ibn Muslim conquered Transoxiana, killed whoever wrote in the Khwarezmian native language and knew of Khwarezmian heritage, history, and culture, killed all of the Zoroastrian priests and burned their books, and proceeded to convert the Afrighids to Islam in the 9th century. In 995 AD, the Afrighids were replaced by the Ma'munids, who were soon after conquered by the Ghaznavids.
